船舶动态定位技术是一种有效的开发海洋资源的方法，在海洋中，由于环境的变化和各种不确定因素，使得单一的传感器的定位精度往往达不到理想的要求。多个传感器的数据融合是当前的一个重要课题。在此基础上，采用多级多传感器数据融合结构，对舰船进行定位。针对船舶的非线性运动，本文提出一种基于船舶定位系统的非线性状态估算方法，为精确的船舶位置提供可靠的保障。
The competition for marine resources is becoming more and more fierce. Ship dynamic positioning technology is an effective method to develop marine resources, however, how to conduct dynamic positioning at sea, to ensure its safety and positioning accuracy. In the ocean, the positioning accuracy of a single sensor often does not meet the ideal requirements because of environmental changes and various uncertainties. Data fusion of multiple sensors is an important topic at present. Based on this structure, a multi-stage and multi-sensor data fusion structure is used to locate the ships. We estimate the nonlinear motion of a ship based on the positioning system of ships. It provides a reliable guarantee for the accurate ship position.
